Answer:
a) 1200 kN/m²
b) 1,200,000 kg/ms²
c) 1.2 × 10⁹ kg/km.s²
Explanation:
Given:
Pressure = 1200 kPa
a) 1 Pa = 1 N/m²
thus,
1000 N = 1 kN
1200 kPa = 1200 kN/m²
b) 1 Pa = 1 N/m² = 1 kg/ms²
Thus,
1200 kPa = 1200000 Pa
or
1200000 Pa = 1200000 × 1 kg/ms²
or
= 1,200,000 kg/ms²
c) 1 km = 1000 m
or
1 m = 0.001 Km
thus,
1,200,000 kg/ms² = 
or
= 1.2 × 10⁹ kg/km.s²

Water waves are not radiant energy. Therefore C is the right answer. Water waves have momentum and energy like electromagnetic waves but don't classify as radiant energy.
Answer:
The specific heat of B is greater than that of A.
Explanation:
The amount of heat lost by A is:
q = m C ΔT
q = (200 g) Ca (100°C - 50°C)
q = 10,000 Ca
The amount of heat gained by B is:
q = (100 g) Cb (50°C - 0°C)
q = 5,000 Cb
Since the heat lost by A = heat gained by B:
10,000 Ca = 5,000 Cb
2 Ca = Cb
So the heat capacity of B is double the heat capacity of A. Answer 5.
